Ever wondered what gives your favorite skincare products their magical touch? Dive into the world of Ascorbyl Methoxycinnamate and discover its transformative benefits, how it's crafted, and what you need to know before it graces your beauty routine.

What is Ascorbyl Methoxycinnamate?

Ascorbyl Methoxycinnamate, also known as L-Ascorbic acid, 6-[(2E)-3-(4-methoxyphenyl)-2-propenoate], is a derivative of Vitamin C (ascorbic acid) combined with methoxycinnamic acid. This ingredient is primarily sourced from the combination of these two compounds, which are known for their beneficial properties in skincare.

The history of Ascorbyl Methoxycinnamate in cosmetics dates back to the ongoing quest for effective antioxidants and skin conditioning agents. Vitamin C has long been celebrated for its antioxidant properties, while cinnamic acid derivatives have been recognized for their UV-absorbing capabilities. By merging these two, scientists aimed to create a compound that could offer the best of both worlds—protection against oxidative stress and enhanced skin conditioning.

The production of Ascorbyl Methoxycinnamate involves a chemical synthesis process where ascorbic acid is esterified with methoxycinnamic acid. This process not only stabilizes the Vitamin C component, making it more resistant to oxidation, but also enhances its ability to penetrate the skin. The result is a potent ingredient that can be effectively incorporated into various cosmetic products, from serums to creams, providing both antioxidant benefits and skin conditioning effects.

The Benefits/Uses of Ascorbyl Methoxycinnamate

In this section, we will delve into the officially recognized cosmetic benefits and uses of Ascorbyl Methoxycinnamate:


Ascorbyl Methoxycinnamate serves as an antioxidant in cosmetic formulations. This means it helps to neutralize free radicals, which are unstable molecules that can cause damage to your skin cells. By combating these free radicals, Ascorbyl Methoxycinnamate helps to protect your skin from environmental stressors like pollution and UV radiation. This protection can contribute to a more youthful and healthy-looking complexion, as it helps to prevent the signs of premature aging such as fine lines and wrinkles.

Skin Conditioning

Another key benefit of Ascorbyl Methoxycinnamate is its skin conditioning properties. This ingredient helps to improve the overall appearance and feel of your skin. It works by enhancing the skin’s texture, making it feel smoother and more supple. Additionally, it can help to maintain the skin’s moisture balance, ensuring that your skin stays hydrated and doesn’t become dry or flaky. This makes it a valuable addition to skincare products aimed at providing a soft, smooth, and well-moisturized complexion.

Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).

Potential Side Effects & Other Considerations

Ascorbyl Methoxycinnamate is generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.

  • Skin irritation
  • Redness
  • Allergic reactions

Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Ascorbyl Methoxycinnamate during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.

Adverse reactions to Ascorbyl Methoxycinnamate are relatively uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure there is no sensitivity or allergic reaction.

Ascorbyl Methoxycinnamate has a comedogenic rating of 1, which means it is unlikely to clog pores and is generally suitable for individuals prone to acne, blemishes, or breakouts. However, individual reactions can vary, so monitoring skin response is essential.
